Steering rack Circlip

[street]

After meticulously bagging ever nut and bolt I’m missing the Circlip that goes over the threaded connection to steering box. Anyone know what size I need measuring around 23mm across the hole?

HI
If its part of the triumph rack you will get it from the spitfire classic parts IE Rimmerbros.com or moss-europe.co.uk
Do you mean it retains the splined pinion in the housing.
